Johto as a region already existed during Kanto. I think the way how misty ends up getting the egg was because it imprinted on her when it hatched.

If I remember correctly the egg was given to ash for winning something. I assume it came from professor elm like in the games. Though togepi cant be normally caught in Johto, I think you catch them in sinnoh but togepi was released before sinnoh.

That’s explains seeing jasmine (gym leader in Johto) being in sinnoh’s sunnyshore City. She has 2 togetic.
